Apple rolls out fourth developer beta of watchOS 4.3

A day after the macOS High Sierra 10.13.4, iOS 11.3, and tvOS 11.3 betas were updated, Apple has made available the fourth developer beta of watchOS 4.3

There continue to be no tangible release notes associated with the watchOS beta. Previous versions of the beta reimplemented the Apple Watch ability to browse an iPhone's music library, after being stricken from watchOS 4.

The new OS appears to fully reinstate media controls lost with watchOS 4, including the ability to "love" or "dislike" songs, delete tracks from a connected library and route audio to AirPlay devices.

The present watchOS build number is 15T5199f, with the previous having number 15T5187e.
